Two parallel lines are crossed by a transversal . What is the value of k?
Answer:
k = 60
Step-by-step explanation:
2k + 11 is a same side corresponding angle, hence
2k + 11 = 131 ( vertically opposite angles )
subtract 11 from both sides
2k = 120 ( divide both sides by 2 )
k = 60
Answer:
Option C. k = 60
Step-by-step explanation:
There are two lines Z and Y and crossed by a transverse x.
We have to find the value of k.
Since opposite angle of ( 2k + 11 ) is corresponding angle of 131°
so opposite angle of ( 2k + 11 ) will be = (2k + 11)
and corresponding angles are equal in measure.
So 2k + 11 = 131
2k = 131 - 11
2k = 120
k = 60
Option C k = 60 is the answer.

Answer:
A y = -x+2
Step-by-step explanation:
To find the slope of the line m we use the formula
slope = (y2-y1)/(x2-x1)
= (-9--7)/(4-2)
= (-9+7)/(4-2)
= -2/2
= -1
When lines are parallel, the slopes are the same. We need to find a line with slope of -1
y = -1x+2 is written in the form y =mx+b where m is the slope
m=-1 so the slope is -1
This line has the same slope so it is parallel to the line above.
Answer:
would be A
Step-by-step explanation:
SLOPE HAS TO BE -1

which graph represents the function f(x)=0.25x+5
Answer:
Option D.
Step-by-step explanation:
Consider the given function
[tex]f(x)=0.25^x+5[/tex]
We need to find the graph of given function.
Substitute x=0 in the given function to find the y-intercept of the function.
[tex]f(0)=0.25^(0)+5[/tex]
[tex]f(0)=1+5[/tex]
[tex]f(0)=6[/tex]
So, y-intercept of the function is 6.
[tex](0.25)^x\rightarrow \infty[/tex] as [tex]x\rightarrow -\infty[/tex]
[tex](0.25)^x\rightarrow 0[/tex] as [tex]x\rightarrow \infty[/tex]
We can concluded that
[tex]f(x)\rightarrow \infty[/tex] as [tex]x\rightarrow -\infty[/tex]
[tex]f(x)\rightarrow 5[/tex] as [tex]x\rightarrow \infty[/tex]
Therefore, the correct option is D.

How do I factor quadratics?
Ok so factoring quadratics is fairly easy once you get the hang of it
So we have a quadratic [tex]x^2+x-2[/tex]
My first question would be what 2 numbers multiply to -2 and add to +1
the answer is 2 and -1
Second question what 2 values multiply to get [tex]x^2[/tex]
the answer x and x
your factored form would be [tex](x-1)(x+2)[/tex]
This is as far as i can explain there is a whole lot about quadratics to be learned. You have to ask your teacher on more information

if x - 4 , x + 2 and 3x + 6 form a geometric sequence, find x.
Answer:
x =7
Step-by-step explanation:
Remark
A geometric sequence always has terms that are separated by a common ratio. For example 3 9 27 81 243 .... Each term is multiplied by a common number and the term before it. In this case the common term is 3. To get the next term after 9, you multiply 9 by 3.To get the common ratio divide the second term by the first and then the third term by the secondEquation
(x + 2)/(x - 4) = (3x + 6)/ (x + 2)
Solution
I would begin this problem by taking out the common factor on the top right term. You'll see why in a second.
(x + 2)/(x - 4) = 3(x + 2)/ (x + 2) Notice the two binomials on the right cancel.
(x + 2)/(x - 4) = 3/1 Cross multiply(x + 2)*1 = 3*(x - 4) Remove the brackets on the right.x + 2 = 3x - 12 Add 12 on both sides.x + 2 + 12 = 3x - 12 + 12 Simplifyx + 14 = 3x Subtract x from both sides14 = 3x - x2x = 14 Divide by 2x = 14/2x = 7write the percent. if necessary, round to the nearest tenth of a percent 6 4/5

Bhavik bought 33 liters of milk and 55 loaves of bread for a total of \$11$11. A month later, he bought 44 liters of milk and 44 loaves of bread at the same prices, for a total of \$10$10. How much does a liter of milk cost, and how much does a loaf of bread cost?
Answer: The cost of 1 liter milk is $ 0.75 and the cost of a loaf of bread is $1.75
Step-by-step explanation:
Let the cost of one liter of milk is m dollar and the cost of one loaf of bread is b dollar.
Since, the total cost of the 3 liter milk and 5 loaf of bread = $ 11
That is, 3 m + 5 b = 11 ----------(1)
And, the cost of the 4 liter of milk and 4 loaf of bread = $ 10
That is, 4 m + 4 b = 10 -----------(2)
4 × Equation (1),
12 m + 20 b = 44 -----------(3)
3 × Equation (2),
12 m + 12 b = 30 --------------(4)
Equation (3) - Equation (4),
We get, 8 b = 14
⇒ b = 14/8 = 1.75
By putting the value of b in equation (1)
We get,
3 m = 11 - 1.75×5 ⇒ m = 2.25/3 = 0.75
Thus, the price of one liter of milk = $ 0.75
And, the price of one loaf = $ 1.75
Answer:
The cost of 1 liter milk is $ 0.75 and the cost of a loaf of bread is $1.75

If f(x)=x+7 and g(x)=1/x-13, What is the domain of (f•g)(x)
Answer:
F(x) = x+7
g(x) = 1/(x-13)
fog(x) = [1/(x-13)] + 7
The denominator of the fraction cannot be equal to zero.
So, the domain of fog(x) is x∈R~{13}
Step-by-step explanation:
To find the domain of (f•g)(x), substitute g(x) into f(x) and identify any values of x that make the expression undefined.
Explanation:The function (f•g)(x) represents the composition of two functions, f(x) and g(x). To find the domain of (f•g)(x), we need to determine the values of x for which the composition is defined.
The composition (f•g)(x) can be written as f(g(x)). Substituting g(x)=1/x-13 into f(x)=x+7, we have f(g(x))=(1/x-13)+7.
The domain of (f•g)(x) consists of all the values of x for which the expression (1/x-13)+7 is defined. Since division by zero is not defined, we need to exclude x=0 from the domain. Additionally, we need to exclude the value x=13 because the expression (1/x-13)+7 would lead to division by zero. Therefore, the domain of (f•g)(x) is x≠0, 13.

Today is my birthday! Four-fifths of my current age is greater than three-quarters of my age one year from now.
Given that my age is an integer number of years, what is the smallest my age could be?
Answer: His smallest age could be 16 years.
Step-by-step explanation:
Since we have given that
Four-fifths of his current age is greater than three-quarters of his age one year from now.
Let his present age be x
So, According to question,

Solve for a in the equation a-17=42
Answer:
a = 59
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Isolate the variable (a). Add 17 to both sides
a - 17 = 42
a - 17 (+17) = 42 (+17)
a = 42 + 17
Simplify. Combine like terms
a = 42 + 17
a = 59
59 is your answer
~
Solve for a (this means they want you to get "a" by itself in the equation)
So:
a - 17 = 42 Add 17 on both sides to get "a" by itself
a - 17 + 17 = 42 + 17
a = 59

0.8660
Step-by-step explanation:
In mathematics, the sine is a trigonometric function of an angle. The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse).
From the triangle shown in the attachment
The sine of an angle =

In a supermarket bin the number of packages of red to peppers to the number of packages of green peppers is in the ratio of 8 is to 13.The peppers are sold in 2 pound packages.What is the least possible weight of red peppers in the bin?
Answer:
16 pounds
Step-by-step explanation:
The ratio of no. of packages of red pepper to no. of packages of green pepper is given 8 is to 13.
So, atleast 8 packages of red pepper are sold
Therefore, least possible weight of red peppers in the bin = 2×8 = 16 pounds.
The least possible weight of red peppers in a supermarket bin with a ratio of 8 to 13 of red to green peppers, where each package weighs 2 pounds, is 16 pounds.
To find the least possible weight, we assume the smallest number of packages that maintain the ratio. Multiplying both numbers of the ratio by 2 pounds gives us the weight of the red and green peppers, but since we want the least possible weight of red peppers, we'll only calculate for red.
Therefore, if we have 8 packages of red peppers, each weighing 2 pounds, the calculation would be:
8 packages × 2 pounds/package = 16 pounds of red peppersSalar's Drama class is performing a play. He wants to buy as many tickets as he can afford. If tickets cost $3.50 each and he has $15.25 to spend, how many tickets can he buy?
Answer: 4 tickets
Step-by-step explanation: If $15.25 is Salar’s total and each ticket costs $3.50, we need to use division to figure out how many tickets Salar can purchase. When we divide 15.25/3.50, we get 4.35 (approximately). Salar can’t have .35 of a ticket, so we round down to 4 whole tickets.

Use slope formula to find the missing coordinate.
(r, 1) and (5, -7) Slope = 8/3
Answer:
r=8
Step-by-step explanation:
The formula for slope is
m = (y2-y1)/ (x2-x1)
Substitute in what we know.
8/3 = (-7-1)/(5-r)
Simplify
8/3 = -8/(5-r)
We can use cross products to help us solve.
8 * (5-r) = 3 * (-8)
divide each side by 8
8/8 * (5-r) = 3 * (-8)/8
5-r = -3
Subtract 5 from each side
5-r-5 = -3-5
-r = -8
Multiply by -1
r = 8
